IDave said:SOR sells bulk nuts and bolts for land cruisers. They are the gold (cadmium plated with chromate coloring) hardware. SOME of those are Toyota parts, and should be available in bulk, from CDan or your dealer, if you can figure out the parts numbers. The issue is figuring out which are what. (Dan and I are working on some of those now).
It looks to me that the nutsandbolts.com hardware isn't cadmium plated.
